"Fenestra che lucive,"
Sung by Enrico Caruso and others.

A Neapolitan song, sung by Caruso, Carreras, Lanza, etc. Modified by T. Giordano.
Rough translation-

The Window that shone now is dark,
A sign that my love is ill.
Her sister looks out and tells me
My love is dead and buried.

She always cried because she slept alone;
Now she sleeps in the company of the dead.

Go to the church, and look into her coffin,
See how your sweetheart is now.
Words of love once came from her mouth,
Now only worms. Alas!

Priest, take care of my little one.
Always keep a lamp lit by her.
